Kriging Surrogate Models for Predicting the Complex Eigenvalues of Mechanical Systems Subjected to Friction-Induced Vibration

Figure 6

Kriging (- -) on two-dimensional parameter space with a 2D linear sample grid (20 × 50) compared to deterministic results (−): real (a, b) and imaginary (c, d) parts of eigenvalues versus for configurations 1 (a, c) and 2 (b, d). Evolution in the complex plan based on kriging metamodel for configurations 1 (e) and 2 (f).
